noticed oil all over cac piping
Hello, I will try to help. If it's all over the back of the engine, from oil pan, and splashing on the catalytic convertor, then it's most likely the turbo oil return line O-ring. The turbo oil return line comes from the turbo down into the back of the engine block just above the oil pan. You can replace it pretty easily. Just remove the clamp that holds the turbo cooler lines together, and remove 2 5 mm allen head screws from the bottom of the turbo oil return line and it twist the line and pull it out. Replace the Oring at the block, and put a new gasket on the line between the turbo and pipe. I also clean the area where the line goes into the block and take a finger of silicone rubber and smear it in the area between the pipe and the block. I've never had one come back leaking after I did that.
I've had 10 years of experience on the car line at 2 Volvo dealerships, Quality level Volvo tech.
I removed timing cover and its all covered in oil. I checked the turbo line and it appears to be all dry. It seems possibly the cam seals??? Is this a common problem?
yes, they do fail, however, the reason for this is most likely the PCV system is stopped up and needs to be service. The flame box sits under the intake and the intake has to be removed to replace the flame box and seal. If it's never been done, then I would recommend it. You can put cam seals in it, but if the crankcase can't breathe, that can make one blow oil out of the engine.
ok thanks. If there is anything else common to look out for on this vehicle please let me know. thanks
